Accounting Policies [Abstract]
Significant Accounting Policies	Note 1 – Significant Accounting Policies
	Nature of Operations
	Sandy Spring Bancorp (the “Company”), a Maryland corporation, is the bank holding company for Sandy Spring Bank (the “Bank”), which conducts a full-service commercial banking, mortgage banking and trust business. Services to individuals and businesses include accepting deposits, extending real estate, consumer and commercial loans and lines of credit, general insurance, personal trust, and investment and wealth management services. The Company operates in the Maryland counties of Anne Arundel, Carroll, Frederick, Howard, Montgomery, and Prince George's, and in Arlington, Fairfax and Loudoun counties in Virginia. The Company offers investment and wealth management services through the Bank’s subsidiary, West Financial Services. Insurance products are available to clients through Sandy Spring Insurance, and Neff & Associates, which are agencies of Sandy Spring Insurance Corporation.
	Basis of Presentation
	The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America (“GAAP”) and prevailing practices within the financial services industry for interim financial information and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and notes required for complete financial statements and prevailing practices within the banking industry. The following summary of significant accounting policies of the Company is presented to assist the reader in understanding the financial and other data presented in this report. Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for any future periods or for the year ending December 31, 2015. In the opinion of management, all adjustments (comprising only normal recurring accruals) necessary for a fair presentation of the results of the interim periods have been included. Certain reclassifications have been made to prior period amounts, as necessary, to conform to the current period presentation. The Company has evaluated subsequent events through the date of the issuance of its financial statements.
	These statements should be read in conjunction with the financial statements and accompanying notes included in the Company’s 2014 Annual Report on Form 10-K as filed with the Securities and Exchange Commission (“SEC”) on March 6, 2015. There have been no significant changes to the Company’s accounting policies as disclosed in the 2014 Annual Report on Form 10-K.
	Principles of Consolidation
	The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Sandy Spring Bank and its subsidiaries, Sandy Spring Insurance Corporation and West Financial Services, Inc. Consolidation has resulted in the elimination of all intercompany accounts and transactions.
	Use of Estimates
	The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, and affect the reported amounts of revenues earned and expenses incurred during the reporting period. Actual results could differ from those estimates. Estimates that could change significantly relate to the provision for loan and lease losses and the related allowance, determination of impaired loans and the related measurement of impairment, potential impairment of goodwill or other intangible assets, valuation of investment securities and the determination of whether impaired securities are other-than-temporarily impaired, valuation of other real estate owned, prepayment rates, valuation of share-based compensation, the assessment that a liability should be recognized with respect to any matters under litigation, the calculation of current and deferred income taxes and the actuarial projections related to pension expense and the related liability.
	Cash Flows
	For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, federal funds sold and interest-bearing deposits with banks (items with stated original maturity of three months or less).
	Pending Accounting Pronouncements
	The FASB issued a standard in May 2014 that provides accounting guidance for all revenue arising from contracts with customers and affects all entities that enter into contracts to provide goods or services to customers. The guidance also provides for a model for the measurement and recognition of gains and losses on the sale of certain nonfinancial assets, such as property and equipment, including real estate. This standard may affect an entity’s financial statements, business processes and internal control over financial reporting. The guidance is effective for the first interim or annual period beginning after December 15, 2016. The guidance must be adopted using either a full retrospective approach for all periods presented in the period of adoption or a modified retrospective approach. The Company is assessing this guidance to determine its impact on the Company’s financial position, results of operations and cash flows.

	Any unrealized losses in the U.S. government agencies, state and municipal, mortgage-backed or corporate debt investment securities at March 31, 2015 are not the result of credit related events but due to changes in interest rates. These declines are considered temporary in nature and are expected to decline over time and recover as these securities approach maturity.
	The mortgage-backed securities portfolio at March 31, 2015 is composed entirely of either the most senior tranches of GNMA, FNMA or FHLMC collateralized mortgage obligations ($160.8 million), or GNMA, FNMA or FHLMC mortgage-backed securities ($185.5 million). The Company does not intend to sell these securities and has sufficient liquidity to hold these securities for an adequate period of time, which may be maturity, to allow for any anticipated recovery in fair value.
	At March 31, 2015 the trust preferred portfolio consisted of one pooled trust preferred security. The pooled trust preferred security, which is backed by debt issued by banks and thrifts, totals $1.1 million with a fair value of $1.0 million. The fair value of this security was determined by management through the use of a third party valuation specialist due to the limited trading activity for this security.
	The income valuation approach technique (present value) used maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs. The methodology and significant assumptions employed by the specialist to determine fair value included:
	Evaluation of the structural terms as established in the indenture;
	Detailed credit and structural evaluation for each piece of issuer collateral in the pool;
	Overall default (.62%), recovery and prepayment (2%)/amortization probabilities by issuers in the pool;
	Identification of adverse conditions specifically related to the security, industry and geographical area;
	Projection of estimated cash flows that incorporate default expectations and loss severities;
	Review of historical and implied volatility of the fair value of the security;
	Evaluation of credit risk concentrations;
	Evaluation of the length of time and the extent to which the fair value has been less than the amortized cost; and
	A discount rate of 11.9% was established using credit adjusted financial institution spreads for comparably rated institutions and a liquidity adjustment that considered the previously noted characteristics.
	As a result of this evaluation, it was determined that the pooled trust preferred security had not incurred any credit-related other-than-temporary impairment (“OTTI”) for the quarter ended March 31, 2015. Non-credit related OTTI on this security, which is not expected to be sold and which the Company has the ability to hold until maturity, was $0.1 million at March 31, 2015. This non-credit related OTTI was recognized in other comprehensive income (“OCI”) at March 31, 2015.
	The methodology and significant inputs used to measure the amount related to credit loss consisted of the following:
	Default rates were developed based on the financial condition of the trust preferred issuers in the pool and the payment or deferral status. Conditional default rates were estimated based on the payment characteristics of the security and the financial condition of the issuers in the pool. Near term and future defaults are estimated using third party industry data in addition to a review of key financial ratios and other pertinent data on the financial stability of the underlying issuer;
	Loss severity is forecasted based on the type of impairment using research performed by third parties;
	The security contains one level of subordination below the senior tranche, with the senior tranche receiving the spread from the subordinate bonds. Given recent performance, it is not expected that the senior tranche will receive its full interest and principal at the bond’s maturity date;
	Credit ratings of the underlying issuers are reviewed in conjunction with the development of the default rates applied to determine the credit amounts related to the credit loss; and
	Potential prepayments are estimated based on terms and rates of the underlying trust preferred securities to determine the impact of excess spread on the credit enhancement, the removal of the strongest institutions from the underlying pool and any impact that prepayments might have on diversity and concentration.
	The following table provides the activity of OTTI on investment securities due to credit losses recognized in earnings for the period indicated:

During the three months ended March 31, 2015, the Company restructured a $0.6 million loan. No modifications resulted in the reduction of the principal in the associated loan balances. Restructured loans are subject to periodic credit reviews to determine the necessity and adequacy of a specific loan loss allowance based on the collectability of the recorded investment in the restructured loan. Loans restructured during 2015 have specific reserves of $0.2 million at March 31, 2015. For the year ended December 31, 2014, the Company restructured $1.6 million in loans. Modifications consisted principally of interest rate concessions and no modifications resulted in the reduction of the recorded investment in the associated loan balances. Loans restructured during 2014 had specific reserves of $0.1 million at December 31, 2014. Commitments to lend additional funds on loans that have been restructured at March 31, 2015 and December 31, 2014 amounted to $0.1 million and $0.1 million, respectively.

SHARE BASED COMPENSATION	3 Months Ended

Share Based Compensation [Abstract]
SHARE BASED COMPENSATION	Note 8 – Share Based Compensation
	At March 31, 2015, the Company had one share based compensation plans in existence, the 2005 Omnibus Stock Plan, which is described in the following paragraph.
	The Company’s 2005 Omnibus Stock Plan (“Omnibus Plan”) provides for the granting of non-qualifying stock options to the Company’s directors, and incentive and non-qualifying stock options, stock appreciation rights and restricted stock grants to selected key employees on a periodic basis at the discretion of the board. The Omnibus Plan authorizes the issuance of up to 1,800,000 shares of common stock of which 988,673 are available for issuance at March 31, 2015, has a term of ten years, and is administered by a committee of at least three directors appointed by the board of directors. Options granted under the plan have an exercise price which may not be less than 100% of the fair market value of the common stock on the date of the grant and must be exercised within seven to ten years from the date of grant. The exercise price of stock options must be paid for in full in cash or shares of common stock, or a combination of both. The board committee has the discretion when making a grant of stock options to impose restrictions on the shares to be purchased upon the exercise of such options. The Company generally issues authorized but previously unissued shares to satisfy option exercises.
	The fair values of all of the options granted for the periods indicated have been estimated using a binomial option-pricing model with the weighted-average assumptions for the periods shown are presented in the following table:
			Three Months Ended March 31,
			2015			2014
	Dividend yield		3.4	%		3.04	%
	Weighted average expected volatility		42.98	%		46.78	%
	Weighted average risk-free interest rate		1.42	%		1.56	%
	Weighted average expected lives (in years)		5.42			5.08
	Weighted average grant-date fair value		$7.63			$8.05
	The dividend yield is based on estimated future dividend yields. The risk-free rate for periods within the contractual term of the share option is based on the U.S. Treasury yield curve in effect at the time of the grant. Expected volatilities are generally based on historical volatilities. The expected term of share options granted is generally derived from historical experience.
	Compensation expense is recognized on a straight-line basis over the vesting period of the respective stock option or restricted stock grant. The Company recognized compensation expense of $0.4 million and $0.4 million for the three months ended March 31, 2015 and 2014, respectively, related to the awards of stock options and restricted stock grants. The intrinsic value of stock options exercised in the three months ended March 31, 2015 and 2014 was $0.1 million and $0.1 million, respectively. The total of unrecognized compensation cost related to stock options was approximately $0.3 million as of March 31, 2015. That cost is expected to be recognized over a weighted average period of approximately 2.4 years. The total of unrecognized compensation cost related to restricted stock was approximately $5.3 million as of March 31, 2015. That cost is expected to be recognized over a weighted average period of approximately 3.7 years. The fair value of the options vested during the three months ended March 31, 2015 and 2014, was $0.1 million and $0.1 million, respectively.
	In the first quarter of 2015, 21,245 stock options were granted, subject to a three year vesting schedule with one third of the options vesting on April 1st of each year. Additionally, 79,860 shares of restricted stock were granted, subject to a five year vesting schedule with one fifth of the shares vesting on April 1st of each year.
	A summary of share option activity for the period indicated is reflected in the following table:
								Weighted

Pension, Profit Sharing, and Other Employee Benefit Plans [Abstract]
PENSION, PROFIT SHARING, AND OTHER EMPLOYEE BENEFIT PLANS	Note 9 – Pension, Profit Sharing, and Other Employee Benefit Plans
	Defined Benefit Pension Plan
	The Company has a qualified, noncontributory, defined benefit pension plan (the “Plan”) covering substantially all employees. Benefits after January 1, 2005, are based on the benefit earned as of December 31, 2004, plus benefits earned in future years of service based on the employee’s compensation during each such year. All benefit accruals for employees were frozen as of December 31, 2007 based on past service and thus salary increases and additional years of service after such date no longer affect the defined benefit provided by the plan although additional vesting may continue to occur.
	The Company's funding policy is to contribute amounts to the plan sufficient to meet the minimum funding requirements of the Employee Retirement Income Security Act of 1974 (“ERISA”), as amended. In addition, the Company contributes additional amounts as it deems appropriate based on benefits attributed to service prior to the date of the plan freeze. The Plan invests primarily in a diversified portfolio of managed fixed income and equity funds.
	The components of net periodic benefit cost for the periods indicated are presented in the following table:
			Three Months Ended March 31,
	(In thousands)		2015		2014
	Interest cost on projected benefit obligation		$	410	$	391
	Expected return on plan assets			-406		-494
	Recognized net actuarial loss			292		48
		Net periodic benefit cost	$	296	$	-55
	Contributions
	The decision as to whether or not to make a plan contribution and the amount of any such contribution is dependent on a number of factors. Such factors include the investment performance of the plan assets in the current economy and, since the plan is currently frozen, the remaining investment horizon of the plan. Given these uncertainties, management continues to monitor the funding level of the pension plan and may make contributions as necessary during 2015.

Financial Instruments With Off- Balance Sheet Risk and Derivatives [Abstract]
FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK AND DERIVATIVES	Note 12 – Financial Instruments with Off-balance Sheet Risk and Derivatives
	The Company has entered into interest rate swaps (“swaps”) to facilitate customer transactions and meet their financing needs. These swaps qualify as derivatives, but are not designated as hedging instruments. Interest rate swap contracts involve the risk of dealing with counterparties and their ability to meet contractual terms. When the fair value of a derivative instrument contract is positive, this generally indicates that the counterparty or customer owes the Company, and results in credit risk to the Company. When the fair value of a derivative instrument contract is negative, the Company owes the customer or counterparty and therefore, has no credit risk. The notional value of commercial loan swaps outstanding was $20.6 million with a fair value of $1.6 million as of March 31, 2015 compared to $20.9 million with a fair value of $1.5 million as of December 31, 2014. The offsetting nature of the swaps results in a neutral effect on the Company’s operations. Fair values of the swaps are carried as both gross assets and gross liabilities in the condensed consolidated statements of condition. The associated net gains and losses on the swaps are recorded in other non-interest income.

LITIGATION	Note 13 – Litigation
	The Company and its subsidiaries are subject in the ordinary course of business to various pending or threatened legal proceedings in which claims for monetary damages are asserted. During 2014, the Company accrued $6.5 million for litigation expenses as a result of an adverse jury verdict rendered in the second quarter of 2014 associated with the actions of a former employee of CommerceFirst Bank, which was acquired in 2012. The Company is currently in the process of appealing the decision. As a result of the appeal process, an additional $0.2 million in legal expenses have been accrued in the first quarter of 2015.
	After consultation with legal counsel, management does not anticipate that the ultimate liability, if any, arising out of any other legal matters will have a material adverse effect on the Company's financial condition, operating results or liquidity.

FAIR_VALUE

FAIR VALUE	3 Months Ended
	Mar. 31, 2015
Fair Value Disclosures [Abstract]
FAIR VALUE	Note 14 – Fair Value
	Generally accepted accounting principles provide entities the option to measure eligible financial assets, financial liabilities and commitments at fair value (i.e. the fair value option), on an instrument-by-instrument basis, that are otherwise not permitted to be accounted for at fair value under other accounting standards. The election to use the fair value option is available when an entity first recognizes a financial asset or financial liability or upon entering into a commitment. Subsequent changes in fair value must be recorded in earnings. The Company applies the fair value option on residential mortgage loans held for sale. The fair value option on residential mortgage loans allows the recognition of gains on sale of mortgage loans to more accurately reflect the timing and economics of the transaction.
	The standard for fair value measurement establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below.
	Basis of Fair Value Measurement:
	Level 1- Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
	Level 2- Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability;
	Level 3- Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity). Changes to interest rates may result in changes in the cash flows due to prepayments or extinguishments. Accordingly, this could result in higher or lower measurements of the fair values.
	A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
	Assets and Liabilities
	Mortgage loans held for sale
	Mortgage loans held for sale are valued based on quotations from the secondary market for similar instruments and are classified as Level 2 of the fair value hierarchy.
	Investments available-for-sale
	U.S. government agencies, mortgage-backed securities and corporate debt
	Valuations are based on active market data and use of evaluated broker pricing models that vary based by asset class and includes available trade, bid, and other market information. Generally, the methodology includes broker quotes, proprietary models, descriptive terms and conditions databases coupled with extensive quality control programs. Multiple quality control evaluation processes review available market, credit and deal level information to support the evaluation of the security. If there is a lack of objectively verifiable information available to support the valuation, the evaluation of the security is discontinued. Additionally, proprietary models and pricing systems, mathematical tools, actual transacted prices, integration of market developments and experienced evaluators are used to determine the value of a security based on a hierarchy of market information regarding a security or securities with similar characteristics. The Company does not adjust the quoted price for such securities. Such instruments are generally classified within Level 2 of the fair value hierarchy.
	State and municipal securities
	Proprietary valuation matrices are used for valuing all tax-exempt municipals that can incorporate changes in the municipal market as they occur. Market evaluation models include the ability to value bank qualified municipals and general market municipals that can be broken down further according to insurer, credit support, state of issuance and rating to incorporate additional spreads and municipal curves. Taxable municipals are valued using a third party model that incorporates a methodology that captures the trading nuances associated with these bonds. Such instruments are generally classified within Level 2 of the fair value hierarchy.
	Trust preferred securities
	In active markets, these types of instruments are valued based on quoted market prices that are readily accessible at the measurement date and are classified within Level 1 of the fair value hierarchy. Positions that are not traded in active markets or are subject to transfer restrictions are valued or adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence. In the absence of such evidence, management uses a process that employs certain assumptions to determine the present value. For further information, refer to Note 2 – Investments. Positions that are not traded in active markets or are subject to transfer restrictions are classified within Level 3 of the fair value hierarchy.
	Interest rate swap agreements
	Interest rate swap agreements are measured by alternative pricing sources with reasonable levels of price transparency in markets that are not active. Based on the complex nature of interest rate swap agreements, the markets these instruments trade in are not as efficient and are less liquid than that of the more mature Level 1 markets. These markets do however have comparable, observable inputs in which an alternative pricing source values these assets in order to arrive at a fair market value. These characteristics classify interest rate swap agreements as Level 2.
	Assets Measured at Fair Value on a Recurring Basis
	The following tables set forth the Company’s financial assets and liabilities at the dates indicated that were accounted for or disclosed at fair value. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement:

At March 31, 2015, impaired loans totaling $31.2 million were written down to fair value of $28.5 million as a result of specific loan loss allowances of $2.7 million associated with the impaired loans which was included in the allowance for loan losses. Impaired loans totaling $29.4 million were written down to fair value of $26.5 million at December 31, 2014 as a result of specific loan loss allowances of $2.9 million associated with the impaired loans.
Loan impairment is measured using the present value of expected cash flows, the loan’s observable market price or the fair value of the collateral (less selling costs) if the loans are collateral dependent. Collateral may be real estate and/or business assets including equipment, inventory and/or accounts receivable. The value of business equipment, inventory and accounts receivable collateral is based on net book value on the business’ financial statements and, if necessary, discounted based on management’s review and analysis. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and client’s business. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the factors identified above. Valuation techniques are consistent with those techniques applied in prior periods.
Other real estate owned (“OREO”) is adjusted to fair value upon transfer of the loans to OREO. Subsequently, OREO is carried at the lower of carrying value or fair value. The estimated fair value for other real estate owned included in Level 3 is determined by independent market based appraisals and other available market information, less cost to sell, that may be reduced further based on market expectations or an executed sales agreement. If the fair value of the collateral deteriorates subsequent to initial recognition, the Company records the OREO as a non-recurring Level 3 adjustment. Valuation techniques are consistent with those techniques applied in prior periods.
Fair Value of Financial Instruments
The Company discloses fair value information about financial instruments for which it is practicable to estimate the value, whether or not such financial instruments are recognized on the balance sheet. Fair value is the amount at which a financial instrument could be exchanged in a current transaction between willing parties, other than in a forced sale or liquidation, and is best evidenced by a quoted market price, if one exists.
Quoted market prices, where available, are shown as estimates of fair market values. Because no quoted market prices are available for a significant portion of the Company's financial instruments, the fair value of such instruments has been derived based on the amount and timing of future cash flows and estimated discount rates.
Present value techniques used in estimating the fair value of many of the Company's financial instruments are significantly affected by the assumptions used. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate cash settlement of the instrument. Additionally, the accompanying estimates of fair values are only representative of the fair values of the individual financial assets and liabilities, and should not be considered an indication of the fair value of the Company.
The carrying amounts and fair values of the Company’s financial instruments at the dates indicated are presented in the following table:

The following methods and assumptions were used to estimate the fair value of each category of financial instruments for which it is practicable to estimate that value:
Cash and Temporary Investments: The carrying amounts of cash and cash equivalents approximate their fair value and have been excluded from the table above.
Investments: The fair value of marketable securities is based on quoted market prices, prices quoted for similar instruments, and prices obtained from independent pricing services.
Loans: For certain categories of loans, such as mortgage, installment and commercial loans, the fair value is estimated by discounting the expected future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and similar remaining maturities. Expected cash flows were projected based on contractual cash flows, adjusted for estimated prepayments.
Accrued interest receivable: The carrying value of accrued interest receivable approximates fair value due to the short-term duration and has been excluded from the table above.
Other assets: The investment in bank-owned life insurance represents the cash surrender value of the policies at March 31, 2015 and December 31, 2014 as determined by the each insurance carrier. The carrying value of accrued interest receivable approximates fair values due to the short-term duration.
Deposits: The fair value of demand, money market savings and regular savings deposits, which have no stated maturity, were considered equal to their carrying amount, representing the amount payable on demand. While management believes that the Bank’s core deposit relationships provide a relatively stable, low-cost funding source that has a substantial intangible value separate from the value of the deposit balances, these estimated fair values do not include the intangible value of core deposit relationships, which comprise a significant portion of the Bank’s deposit base.
Short-term borrowings: The carrying values of short-term borrowings, including overnight, securities sold under agreements to repurchase and federal funds purchased approximates the fair values due to the short maturities of those instruments.
Long-term borrowings: The fair value of the Federal Home Loan Bank of Atlanta (“FHLB”) advances and subordinated debentures was estimated by computing the discounted value of contractual cash flows payable at current interest rates for obligations with similar remaining terms. The Company's credit risk is not material to calculation of fair value because the FHLB borrowings are collateralized. The Company classifies advances from the Federal Home Loan Bank of Atlanta within Level 2 of the fair value hierarchy since the fair value of such borrowings is based on rates currently available for borrowings with similar terms and remaining maturities. Subordinated debentures are classified as Level 3 in the fair value hierarchy due to the lack of market activity of such instruments.
Accrued interest payable: The carrying value of accrued interest payable approximates fair value due to the short-term duration and has been excluded from the previous table.

Segment Reporting [Abstract]
SEGMENT REPORTING	Note 15 - Segment Reporting
	Currently, the Company conducts business in three operating segments—Community Banking, Insurance and Investment Management. Each of the operating segments is a strategic business unit that offers different products and services. The Insurance and Investment Management segments were businesses that were acquired in separate transactions where management of acquisition was retained. The accounting policies of the segments are the same as those of the Company. However, the segment data reflect inter-segment transactions and balances.
	The Community Banking segment is conducted through Sandy Spring Bank and involves delivering a broad range of financial products and services, including various loan and deposit products to both individuals and businesses. Parent company income is included in the Community Banking segment, as the majority of effort of these functions is related to this segment. Major revenue sources include net interest income, gains on sales of mortgage loans, trust income, fees on sales of investment products and service charges on deposit accounts. Expenses include personnel, occupancy, marketing, equipment and other expenses. Non-cash charges associated with amortization of intangibles related to the acquired entities amounted to $0.1 million and $0.3 million in for the three months ended March 31, 2015 and 2014, respectively.
	The Insurance segment is conducted through Sandy Spring Insurance Corporation, a subsidiary of the Bank, and offers annuities as an alternative to traditional deposit accounts. Sandy Spring Insurance Corporation operates Sandy Spring Insurance, a general insurance agency located in Annapolis, Maryland, and Neff and Associates, located in Ocean City, Maryland. Major sources of revenue are insurance commissions from commercial lines, personal lines, and medical liability lines. Expenses include personnel and support charges. Non-cash charges associated with amortization of intangibles related to the acquired entities was not significant for the three ended March 31, 2015 and 2014, respectively.
	The Investment Management segment is conducted through West Financial Services, Inc., a subsidiary of the Bank. This asset management and financial planning firm, located in McLean, Virginia, provides comprehensive investment management and financial planning to individuals, families, small businesses and associations including cash flow analysis, investment review, tax planning, retirement planning, insurance analysis and estate planning. West Financial currently has approximately $1.1 billion in assets under management. Major revenue sources include non-interest income earned on the above services. Expenses include personnel and support charges. Non-cash charges associated with amortization of intangibles related to the acquired entities was not significant for the three ended March 31, 2015 and 2014, respectively.

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations
	Sandy Spring Bancorp (the “Company”), a Maryland corporation, is the bank holding company for Sandy Spring Bank (the “Bank”), which conducts a full-service commercial banking, mortgage banking and trust business. Services to individuals and businesses include accepting deposits, extending real estate, consumer and commercial loans and lines of credit, general insurance, personal trust, and investment and wealth management services.

Basis of Presentation	Basis of Presentation
	The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America (“GAAP”) and prevailing practices within the financial services industry for interim financial information and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and notes required for complete financial statements and prevailing practices within the banking industry. The following summary of significant accounting policies of the Company is presented to assist the reader in understanding the financial and other data presented in this report. Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for any future periods or for the year ending December 31, 2015. In the opinion of management, all adjustments (comprising only normal recurring accruals) necessary for a fair presentation of the results of the interim periods have been included. Certain reclassifications have been made to prior period amounts, as necessary, to conform to the current period presentation. The Company has evaluated subsequent events through the date of the issuance of its financial statements.
	These statements should be read in conjunction with the financial statements and accompanying notes included in the Company’s 2014 Annual Report on Form 10-K as filed with the Securities and Exchange Commission (“SEC”) on March 6, 2015. There have been no significant changes to the Company’s accounting policies as disclosed in the 2014 Annual Report on Form 10-K.
Principles of Consolidation	Principles of Consolidation
	The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Sandy Spring Bank and its subsidiaries, Sandy Spring Insurance Corporation and West Financial Services, Inc. Consolidation has resulted in the elimination of all intercompany accounts and transactions.
Use of Estimates	Use of Estimates
	The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, and affect the reported amounts of revenues earned and expenses incurred during the reporting period. Actual results could differ from those estimates. Estimates that could change significantly relate to the provision for loan and lease losses and the related allowance, determination of impaired loans and the related measurement of impairment, potential impairment of goodwill or other intangible assets, valuation of investment securities and the determination of whether impaired securities are other-than-temporarily impaired, valuation of other real estate owned, prepayment rates, valuation of share-based compensation, the assessment that a liability should be recognized with respect to any matters under litigation, the calculation of current and deferred income taxes and the actuarial projections related to pension expense and the related liability.
Cash Flows	Cash Flows
	For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, federal funds sold and interest-bearing deposits with banks (items with stated original maturity of three months or less).
Adopted Accounting Pronouncements	Pending Accounting Pronouncements
	The FASB issued a standard in May 2014 that provides accounting guidance for all revenue arising from contracts with customers and affects all entities that enter into contracts to provide goods or services to customers. The guidance also provides for a model for the measurement and recognition of gains and losses on the sale of certain nonfinancial assets, such as property and equipment, including real estate. This standard may affect an entity’s financial statements, business processes and internal control over financial reporting. The guidance is effective for the first interim or annual period beginning after December 15, 2016. The guidance must be adopted using either a full retrospective approach for all periods presented in the period of adoption or a modified retrospective approach. The Company is assessing this guidance to determine its impact on the Company’s financial position, results of operations and cash flows.
